You are at the music store looking for CDs. The store has CDs for $10 and $15. You have $55.00 to spend.?

Write an equation that represents the diff. Numbers of $10 and $15 CDs that you can buy.

Let x = number of $10 CDs
Let y = number of $15 CDs

The equation for purchasing $55 of CDs is expressed as:

10x + 15y = 55

This can be simplified into:

2x + 3y = 11

The possible answers to this equation are:

x = 1, y = 3
x = 4, y = 1

So, you can buy (1 $10 CD and 3 $15 CDs) or (4 $10 CDs and 1 $15 CD) for $55.

Hope this helps!
